Note: The displacement ratios selection, so called"matching", between the Roots Vacuum Pump and the backing pumps which are based on the working vacuum value of the vacuum system with these pumps, which not only ensure that the max pressure difference should not exceed "Max.Allowed Pressure Difference"under long term running, but also must guarantee the Roots Vacuum Pump being in a larger working range, as well as the backing vacuum pumps working properly.
